System.TypeLoadException: Could not load type of field 'Microsoft.VisualStudio.TestPlatform.ObjectModel.PlatformEqtTrace:TraceSourceLevelsMap' (1) due to about vstest HOT 6 CLOSED

Run into the same problem, but I think it's more likely to be a problem with vstest, see issue #4657.

from vstest.

I have transfered the issue to vstest repo because I have confirmed issue is linked to it. Uninstalling .NET 7 fixes the issue.

Hi @Romfos,

Was the code working before? Have you only bumped MSTest or have you changed something else (e.g. version of VS, version of test SDK...)? I see you are using net462, are you using the AppDomain feature?

Is it possible to have a small reproducer for us to investigate the issue?

from vstest.

Hi @Evangelink , yes, please:

repo
https://github.com/Romfos/mstest-repo

build:
https://github.com/Romfos/mstest-repo/actions/runs/5961090424/job/16169633189

note: looks like issue started after .net sdk latest patch applying

from vstest.

Thanks for the quick reply, I confirm that I can repro the issue (only on Linux and net462):

I will investigate the issue.

This is probably the same issue as #4549 and #4627, we inserted fix for that into servicing on 7.0.401, and it should be in the next service release. (this has links to the insertion pr #4549 (comment))
